Yan Nawa, in the past, was called Ban Thawai (Tavoy village, บ้านทะวาย) or Ban Khok Khwai (water buffalo pen village, บ้านคอกควาย) due to a large concentration of Tavoy people who often brought water buffaloes to market for trade. It became Amphoe Ban Thawai during King Chulalongkorn period, and was part of the Phra Pradaeng province. When that province was abolished in 1932, its northern parts were added to Phra Nakhon (Bangkok) province. Ban Tavoy was then renamed to Amphoe Yan Nawa in agreement with the earlier rename of Wat Ban Thawai to Wat Yan Nawa. It became a khet in 1972 and the present-day kwaengs were devised in 1975. On 9 November 1989 parts of Yan Nawa were split off to form two new districts, Sathon and Bang Kho Laem. Wat Yan Nawa, the temple from which the district name inherits, is now located in Sathon district.
